copy eclipse projects to OS X

The projects from the old 3.2 eclipse installation (linux) don't show up in the new 3.4 one (OS X). The projects are part of a Mercurial repository. The clone worked fine from view of Mercurial. But eclipse didn't show this projects.

Import from the workspace was not possible. It worked only after I moved this projects outside the workspace. But the projects should be locate inside the workspace. All machines should have the same file structure.

Adding the missing project again made the complete project with all is content visible. The original and the new .project file are equal.

A look at /Applications//eclipse/Eclipse.app/Contents/MacOS/eclipse.ini didn't reveal any obvious information about used projects.

I will try this on linux and Windows after I updated eclipse to 3.4 on this machines.
